Enter the samples domain. You'll see a "No Results" page. After running any sample, change the filter in the top right corner from "Open" to "Closed" to see the list of the completed workflows.

Click on a RUN ID of a workflow to see more details about it. Try different view formats to get a different level of details about the execution history.

Each sample has specific requirements for running it. The following sections contain information about how to run each of the samples after you've built them using the preceding instructions.

Workflow Worker:

./bins/workflowWorker

Activities Worker:

./bins/activityWorker

Initiate Transfer:

tctl wf start --tl transfer --wt transfer --et 1200  --if ./transferRequest.json

Initiate Transfer Specifying Id of "T1":

tctl wf start --w T1 --tl transfer --wt transfer --et 1200  --if ./transferRequest.json

Initiate Transfer Specifying Id of "T1" and "reject duplicate workflow ID" ID reuse policy:
